IMPROVEMENT FLUTINGMACHINES- The Schedule referred to in theseLettex's Patent and making part of the same.

To all whom 'it may concern 'Be it known that I, CHARLES E. LuHonMEsyof the city and State of New York, have invented 'and made a new and useful Improvement in Fluting-Machineshand the following is declared to be a correct description thereof.

'lhe object of this invention is to lessen the cost of construction, and render the machines lighter and less liable to get ont of repair.

' I provide a pipe-shaped bearing for the upper roller at the top of the standard, upon which standard is a i the line c x,- and Figure 3isan end view of the tinted sheet-metal roller upon the rigid hollow arm.,

'lhe base a, of any desired shape, carries the vertical standard b, at the upper end of -whch is a pipeshaped bearing, c, for the hollow shaft d of the upper roller e. p p

4This roller c is madeof a sheet-metal tube, corrugated to form the flutes. This, however, does not form my invention.

The sliding-sleeve j, around thecolumn or standard b, is kept up by a spring, i, and carries a hollow rigid arm, h, that does not revolve, but the lower roller k,

made of a tinted tube, as aforesaid,.and placed upon l the hollow arm, does revolve with the roller e,when that is turned by a crank-handle, l, applied .to said shaft d of the roller e: p

` The shaft d is `open for the introduction of a heater, andthe sliding-sleeve f and standard b are formed wit-h openings at n.,on line with the arm h, for the purpose of allowing the heating-bolt to be introduced at this end, and the rings o or caps of the rollers prevent th bolt passing in too far.

The rollers are opened by pressing down the roller i k, rigid arm h, and sliding-sleeve f.

I guide the sliding-sleeve f by a pin, r, passing through it, and moving in aver-tical slot in the standal'd b.

The pin yr may have a head upon it, so as to he revolved and draw upon a chain or wire cord within the standard b, and wind the same np sufficiently to draw down the sliding-sleeve f, and thereby separate the rollers; or this revolving-pin fr might act upon a pinion or a camrfor accomplishing `the same o hject.

l claim as my invention- Y 1. The standard b, and pipe-shaped bearing c at its ,upper end, for the shaft d of the roller c, in combina- 2. The pin r, passing through the sliding-sleeve f,

and a slot in the column la, and forming a guide, in combination with the' rollers e k, and chain, or its equivalent, for drawing the roller hdown when the pin yr is turned, as set forth.

3. `The arrangement of the rigid arm h, made hollow for receiving the heater, with the rotating sleeve or roller It, of a pair of Hating-rollers, substantially as specified.
